The synthesis and characterization of a mixed metal ruthenium(ii)/gold(iii) complex bridged by tetrapyridophenazine (tpphz) are described. It is isostructural and isoelectronic to the well-known photocatalysts with palladium(ii) or platinum(ii). Concentration dependent (1)H-NMR spectroscopy and XRD studies show that the electrostatic repulsion between the gold(iii) moieties exceeds the attracti...

A synthetic route with two consecutive coordination chemistry steps on a solid support affords tris-heteroleptic ruthenium(II) polypyridyl complexes with high purity and in good yields. As an application we report the identification of a nanomolar acetylcholinesterase inhibitor from a small ruthenium complex library synthesized on Lanterns.

A readily available pincer ruthenium(II) complex catalyzes the selective monoalkylation of (hetero)aromatic amines with a wide range of primary alcohols (including pyridine-, furan-, and thiophene-substituted alcohols) with high efficiency when used in low catalyst loadings (1 mol %). Tertiary amine formation via polyalkylation does not occur, making this ruthenium system an excellent catalyst ...

II 1 A group of five new ruthenium(II) bipyridine heterochelates of the type [Ru (bpy) L] 1a–1e have been synthesized (bpy52,292 bipyridine; L5anionic form of the thiol-based imine ligands, HS–C H N=C(H)C H (R) (R5OMe, Me, H, Cl, NO ). The complexes 6 4 6 4 2 1a21e are 1:1 conducting and diamagnetic. The complexes 1a21e exhibit strong MLCT transitions in the visible region and intra-ligand tran...

A new ruthenium(II) complex has been developed for detection of biomolecules. This complex is highly selective for histidine over other amino acids and has been applied to protein staining in an SDS-PAGE gel.

A novel ruthenium(II) complex with specific luminescent selectivity towards hybrid G-quadruplex DNA was developed that can easily be distinguished by the naked eye without further treatment.

Dye-sensitized solar cells transform light into electricity. One commonly used dye is a ruthenium complex. However, the use of has been shown to have several disadvantages. In this study, via singular spectrum analysis using HypSpec software, we determined formation constants and calculated individual electronic spectra species iron(III) with ligands (1,2-diaminoethane, 1,3-diaminopropane, 1,4-...

Carbon monoxide (CO) has recently been shown to impart beneficial effects in mammalian physiology and considerable research attention is now being directed toward metal-carbonyl complexes as a means of delivering CO to biological targets. Two ruthenium carbonyl complexes, namely trans-dicarbonyldichlorido(4,5-diazafluoren-9-one-κ(2)N,N')ruthenium(II), [RuCl2(C11H6N2O)(CO)2], (1), and fac-tricar...

Dye-sensitized solar cells (DSCs) have been explored for more than a decade for realistic photovoltaic applications owing to their high conversion efficiency and low cost. Molecular engineering of the sensitizers to achieve high photovoltaic performance and long-term device stability is one of the critical strategies. Since the first high-efficiency ruthenium-based sensitizer, cis-di(thiocyanat...
